A groundbreaking neuroimaging study published in the scientific journal Psychophysiology suggests that people who regularly practice mindfulness meditation are more likely to notice subtle bodily sensations, but this heightened awareness does not translate into greater accuracy when detecting real versus imagined stimuli. The research provides intriguing insights into how mindfulness affects the brain’s processing of sensory information—raising both exciting possibilities and important questions for Thai practitioners and health professionals interested in meditation for well-being (PsyPost).
Mindfulness meditation, a practice with ancient roots in Buddhist traditions and increasingly popular in modern Thailand, has long been associated with improved emotional regulation, reduced stress, and enhanced general well-being (Wikipedia: Mindfulness). However, scientific understanding of the precise mechanisms by which it exerts these benefits has remained limited. This latest study, spearheaded by a researcher at the Institute of Computer Science and Campus Institute Data Science at Georg-August-Universität Göttingen, contributes to a nuanced understanding: meditation appears to lower the ‘threshold’ for perceiving physical sensations, effectively making the brain more “open” or responsive to subtle stimuli. Importantly, though, this openness does not necessarily make individuals more precise in detecting what is real versus what is imagined.
The research involved 31 experienced mindfulness meditators and 33 non-meditator controls—specifically, avid readers who regularly spent at least five hours per week engaging in sustained attention activities involving books. Both groups were matched for age, gender, handedness, and the absence of any neurological or psychiatric conditions. Participants underwent a carefully designed somatosensory signal detection test: faint electrical stimulations were delivered to a finger in some trials, while other trials delivered no stimulation at all. Occasionally, these were paired with brief but uninformative flashes of light. After each trial, participants were queried about their perception—had they felt a touch, or not?
The core findings surprised researchers. While it was hypothesized that long-term meditators might exhibit sharper discriminative ability—becoming more sensitive or accurate—the results showed no improvement in sensitivity compared to the control group. Instead, meditators displayed a lower “decision threshold”: they were simply more likely to report feeling a touch, regardless of whether it was present. This greater readiness to perceive faint sensations was further confirmed via neuroimaging. Electroencephalography (EEG) scans demonstrated significantly lower prestimulus alpha-band activity in meditators’ somatosensory cortices, a brain pattern associated with enhanced excitability and reduced sensory gating. In practical terms, this neurophysiological state means the brain is less restrictive about what is allowed into conscious awareness, resulting in both more accurate hits and more false alarms (PsyPost article).
“This dissociation suggests the practice alters sensory gating or decision-making rather than raw perceptual acuity,” explained the study’s lead author, reflecting on years of inquiry into the science of contemplative practice. The researchers further contextualised that while mindfulness meditation increases bodily awareness—a result mirrored in participants’ self-reported scores for interoceptive sensibility and emotional awareness—it doesn’t enhance “raw” sensory performance in controlled testing conditions. Instead, meditators were simply more willing to say “yes” to subtle, near-threshold sensations.
Thailand has a rich heritage in mindfulness practices, exemplified through the widespread use of Vipassana and other meditation forms in Buddhist monastic and lay settings (Thai Studies Journal). Many Thais pursue these practices for various reasons: spiritual growth, emotional balance, or as a health intervention for stress and anxiety. With increasing adoption of mindfulness in Thai schools, hospitals, and workplaces, understanding the actual cognitive and physiological effects is vital for educators, healthcare providers, and policymakers (Bangkok Post: Mindfulness in Schools). The new findings, while affirming the enhanced bodily awareness cultivated by meditation, counsel a degree of nuance when interpreting subjective bodily experiences—for example, physical sensations interpreted during meditation or therapeutic activities.
The technical aspects of the study deserve attention for Thai readers interested in the science behind the headlines. EEG, or electroencephalography, provides real-time tracking of brain electrical activity. The research in question focused on alpha-band oscillations—brain waves in the frequency range of 8–12 Hz, known to be involved in regulating attention and sensory gating (PubMed Central: Alpha Oscillations). Lowered alpha-band activity, as seen in meditators, is often associated with increased cortical excitability and a more “present-centered” processing of incoming stimuli. However, as the researchers note, this openness can result in more “false alarms”—reporting sensations that did not actually occur—suggesting that the meditative brain is less filter-oriented and more receptive to incoming signals, whether real or imagined.
Importantly, the study’s design comes with limitations. It was cross-sectional, meaning it compared two groups at a single time point, rather than following individuals before and after they began meditating. As such, while correlations are strong, causation cannot be established: it is possible that people with naturally lower sensory gating are more likely to take up meditation in the first place. The reading control group, while carefully chosen, may still differ in meaningful ways from the meditators, given potential confounding lifestyle, social, or psychological factors.
Yet, the robust integration of behavioral tests, neuroimaging, and self-report questionnaires provides an impressive multi-modal look at how mindfulness practice affects the brain and subjective experience. On questionnaires, meditators reported greater interoceptive sensibility—greater conscious awareness of internal bodily signals and less avoidance or worry about uncomfortable sensations—as well as lower emotional suppression. These subjective reports, in combination with the EEG findings, offer a compelling picture of the “mindful” brain: more attuned, more open to sensation, but not necessarily more accurate in detecting the reality of subtle physical events.
For Thai society, which is grappling with rising stress levels, especially in the aftermath of the COVID-19 pandemic, the popularity of mindfulness-based interventions continues to soar. Thai schools increasingly incorporate mindful breathing and meditation into curricula (Bangkok Post Education), while hospitals and community centers offer similar programs for stress reduction and emotional resilience (Ministry of Public Health Thailand). This study reminds practitioners, educators, and healthcare professionals that while such interventions foster embodied awareness and emotional openness—benefits well-established in numerous scientific and Buddhist sources—they must also be approached critically. Enhanced awareness of bodily signals can sometimes lead to over-attribution of meaning, potentially resulting in misinterpretations or psychosomatic responses.
Historically, Thai culture has emphasized the importance of bodily awareness and self-reflection, particularly in Buddhist practice. The concept of “sati,” or mindfulness, is central to Theravada Buddhism and underpins both traditional healing systems and modern mental health care (Encyclopedia of Buddhism: Mindfulness). The fusion of these ancient concepts with modern neuroscience, as exemplified in this study, encourages a scientifically-informed appreciation of traditional wisdom while recognizing the complexities of the embodied mind.
Looking forward, the study’s authors highlight the need for further research with larger, longitudinal samples and more precise neuroimaging techniques to determine the causal relationships and boundary conditions of these effects. For Thailand’s mental health sector, such rigor is necessary to ensure public messaging about mindfulness is evidence-based. There may be opportunities for collaborative research between Thai meditation centers, universities, and hospitals to further examine these effects in local populations, potentially considering variations across different Buddhist traditions and practice intensities.
For Thai readers, practical recommendations emerge from this research. Mindfulness meditation remains a valuable practice for cultivating emotional regulation and body awareness. However, practitioners and teachers should be aware that increased perception of bodily signals does not necessarily mean increased accuracy. Whether engaging in traditional Buddhist retreats, school-based mindfulness programs, or clinical interventions, it is wise to combine embodied mindfulness with critical reflection—consulting reliable resources and mental health professionals as needed—to properly interpret bodily sensations and avoid unnecessary anxiety over ambiguous physical cues.
In summary, this new neuroimaging study clarifies that mindfulness meditation can make the brain more receptive and alert to faint bodily sensations, but this does not mean the signals are always accurate. For Thailand, a nation deeply rooted in mindfulness traditions, such findings reinforce the value of practice while also encouraging scientific literacy and careful interpretation of subjective experience. As research continues to bridge ancient practice and modern science, Thais can continue to cultivate mindful awareness—tempered with discernment and guided by both tradition and evidence.
